List vector IDs

Returns up to 100 IDs at a time by default in sorted order (bitwise "C" collation). If the limit parameter is set, list returns up to that number of IDs instead. Whenever there are additional IDs to return, the response also includes a pagination_token that you can use to get the next batch of IDs. When the response does not include a pagination_token, there are no more IDs to return.

For guidance and examples, see List record IDs.

Note: list is supported only for serverless indexes.
